I think if I don't beat the market in 2013, I'm gonna throw in the towel on the whole MI enterprise, which I've been doing for nearly two decades. OMG, it's been that long, and I've all but proven that I am not smarter than the market, despite a consistent, disciplined long-term mechanical approach.

If I do stop MI, I'll just stick to a simple mix of market ETFs (primarily SPY, with a little DIA, QQQ, etc.) and keep an eye on the Arezi ratio to adjust my leverage once in a while.

I think the only reason why I haven't done this long ago is because it's fun to put my hands in the cookie jar. I like trying to beat the market, even though I can't seem to do so over the long run. I can still taste how sweet it was those times I trounced it, and seem pretty good at blocking out the very bad but predictable taste of losing worse whenever the market turned south.

Bottom line I gotta ask myself: is sticking to mechanical investing really just an emotional decision after all is said and done?
